EDUCATIONAL SIGN.

Application led October 30, c1922. Serial No. 597,948.

To @ZZ whom it may concern:

'Be it'known that l, CARL A; FAIRBANKS, a citizen ofthe United States, residing .at Vichita, in the count-y of lSedgwick and State of Kansas, have invented new anduseful Improvements in Educational Signs, of which the following isa specification. n

My present invention has'reference to improvements in electric signs and is particularly directed to signs Jfor optical advertising and demonstrating purposes.

'In carrying out my present invention, l 'proposeto produce an electrically operated sign having upon its outer fa-ceV the lrepresentation of a persons head and having a picture directly in the line of vision thereof,

the eye portion of the representation being arranged upon a revolublg'J disk, the picture or other representation being likewise arranged upon a reyoluble disk, both of said disks being normally concealed so that only the eye `andthe picture thereof is disclosed, while `means is provided for revolving the `disks intirned relation to each other and for flashing light rays lfrom the eye on to the picture orrepresentation, the anatomical drawingsgofthe eye and the views on the disk representing respectively a normal eye and a normal picture as viewedby `a norimalfeye, a arsighted eye ,and a distortedv picture as viewed by thegl'arsighted eye, a nearsighted eye and a distorted picture as viewed by the nearsighted eye, `and an astigmated eye and a picture aS viewed bythe eye, addition 'to instructions with respect to the normal and distorted eyes, together with the manner in which the latter may be corrected, which latter are vflashed successively on the sign as the respective disks are revolved to bring thefdrawings `of the `eye and the pictures into view'.v

The foregoing, and many other objects which will present themselves as .the nature of the invention is betterunderstood, vmay be accomplished by a construction, combination andoperative association of parts such as is disclosed lby the drawings which' accompany and which `form part of this application. i l y y Int-he drawings y y lFigure 1 is a front elevationof lan optical sign in accordance with this invention.

Figure 2 is a view with the face plate removed. v` Figure-3 is a sectionaflview 'on the `line 3 3 of Figure2.

Figure 4 is a sectional view on the line `4--4 of Figure 2.

The remaining figures illustrate details. As disclosed 'by the drawings, l make use of a substantially rectangular .casing 1; On the outer face 2' of the casing there is printed the 'name of the "company employing the line of vision with respect to the eyel of the yfigure there is a round opening 4. Preferably the face plate 2 is constructed'or glass which, however is rendered translucent. eX-

cept at certain points lthereon in whichthere are imprinted instructions with respect to` .a normal eye, indicated by the numeral 5, instructions with respect to a farsifghted eye, indicated by the numeral 6,-instructions with respect to a nearsighted eye, indicated by the ynumeral 7 ,instructions with Vrespect to `an`astigmated eye, indicated by the nu-` moral 8',` and instructions` as to the manner in vwhich defected eyes may be remedied, indicated by the numeral `9. Light from 'elec- 'tric bulbs is flashed thro-ugh the letters rep'- senti-ng these instructions'in' a manner which will presently be described. 'y v VIn the casing. 1 there is an electrically driven motor 10. On the shaft of this motor there are reducing gears arranged in a suit'- able housing 11. As a matter of fact the 'Shaft of the motor is in two sections, clutch y-means 12 being provided for connecting or disconnecting the sections. The shaft of the motor also actua-tes a lasher 13, the same heing of `a construction lsimilan'to that" disclosed Vin U. S. `Patent. No. 1,343,141, grant. ed P. J. Kenagy, on JunepS, 1920;,

On the shaiitdlV there is secured fa cam star wheel 14.y The wheel has tourcamshapedvarms, and the walls between the arms aremounted. `Pivoted on a lsuitable support in the casing, as atk 15 thereyis a lever 16.

. Secured on the shaft 21v there vis a preferably l Onthe lever lthere is jouirnaled a roller 17 designed to be engaged chain 33 that engages a second sprocket wheel 34 on a shaft 35. The shaft 35 has keyed thereon apreferably glass disk 36, and on this diskthere are imprinted at four separate points views of any desired character, the said views being indicated for distinction bythe numerals 37, 38, 39 and 4() respectively. Also on the shaft there is a wheel 41 having. its periphery provided with four equi-distantly spaced V-shaped notches y42 which are designed to be engaged by the V-shaped end 43 of a flat spring 44, one end of the spring being suitably supported in the housing. The springs engaging the notched wheels are .dcsi'gnedto hold the disks 23 and 36 from accidental turning.

In the housing to the rear of the respective signs 5, 6, 7, 8 and 9 there are lamp boxes 46, 47, 48, 49 and 50 respectively,and

in each of these boxes there is an electric bulb 51 respectively. In addition to the bulbs 51 there is a bulb 52 which is always lighted aslong as the sign is in operation and which is arranged directly opposite the representation on the disk 36'when the latter is brought opposite the opening 4 in the fac-e plate 2. In this connection it should be stated that the drawings ofthe eye on the disk 23 are so positioned that the samev are successively brought opposite the opening 3.in the yface plate 2. An additional bulb 53 is arranged directly opposite the disk 23 and this bulb is lighted when the pictures of the eye on the disk 23 are brought opposite the opening in the casing'therefor simul-` taneously with a view on the disk 36. The result is that rays of light are passed from the bulb through the opening opposite the disk 23 to be reflected on the view ldisclosed through the opening in the casing on the disk 36.

As previously stated, I make use of the electric contrivance set forth in n S. Patent No. 1,343,141, so that a. detailed description of this apparatus is not deemed necessary The disks are slowly revolved and are held for a determined length of time v incident to the lost motion provided by the operating shaft when the notched wheels 28 and 41 are engaged by the V-shaped ends of-the spring arms 31 and 44, and when the normal eye 5 on the disk 23 is brought opposite the normal view 37 on the Vdisk 36 only the bulb 53 and the bulb 48 which is arranged to the rear of the printed inscription disk36, the lamp 53 and the lamp 42, which is opposite the printed instructions regarding the farsighted eye, and the lamp which is opposite the instructions regarding the manner in whichsuch fai-sighted eyesmay be remedied, are illuminated. The view displayed is distorted to show how the same is seen by a person having farsighted eyes. Vhen the disks are again moved to bring-a nearsighted eye through the opening in the casing and a view or picture first seen'by ya farsighted eye is brought opposite the opening 4 the lamp y53 is flashed as is the lamp 48, the lamp 42 having been extinguished, the lamp 50, however, being stillv lighted. As the disks are again revolve-dto bring to view an astigmated eye, and a picture as seen by such eye the lamp 50 is lighted, the lamp 53 flashing light between the openings 3 and 4, and the lamp to the rear yof the instructions regarding the manner in which (such defective eye may be remedied is also lighted.v Vhen the rdisks are'again revolved to bring to view a normal eye and a picture as viewed by a normal eye all of the lamps, except the lamp 45 and the flasher bulb 53 are eXtinguished,the. last mentioned lamps being illuminated. 1

The bulb52arranged to the' rear of the i pictures on the disk 36 is also illuminated as each of the said pictures is brought to view, and from the foregoingdescription when taken in connection with they drawings, it will-benoted that Ihave produced an eflicient optical' sign or advertising device which is of a comparatively simple construction, but which will attract .attention to effectively advertise the business of the opticianusingthe sign. It is further to be understood thatthe nature of the'invention issuch as to render the same susceptible to such minor changes as fall within the scope of the attached claims.

Having described the invention, vI claim 1. In a device for the purpose set forth, a casing, a motor operated shaft therein, comprising sections, reducing means whereby one of said sections is turned at a less rate of speed than the other, disks journaled'in the casing to the rear of the openings, means actuated by the motor shaftv for imparting an intermittent rotary movement to oneof the disks, means between the disks whereby the same are simultaneously .rotated so that l scribed, a casing havingspaced openings ink the lface thereof, ,a motor operated shaft,

loomprisingltwo sections, means whereby one of said sections is turned at a .less rate of speed Vthanthe other section, disks having views thereon journaled in the casingv and disposed to the rear ofthe openings therein,

means between theslower moving section of the shaft and. one of the disks for imparting an intermittent rotary motion to said disk, spring means return-ing said niotion'impartmg means to initial-position, means'between ythe disks whereby the 'same are simultaneously rotated, means for momentarily -halting the disks when the views are brought opposite the openings, and means for illuminating the disks when in such position.
